I've had time issues putting everything back on when I first got it. It's now been about 6 months and I can have the sides and back in within about 10 min or less. Regarding the back window, it's actually easier to undo the bottom of the sides and unzip the top back about 6-ish inches. It's easier to get the zippers to line up in the back. But like XTRyan said, once it's been on and in the sun for a while, the fabric will stretch and make it easier.
